21 GBOn pressure reducers equipped with a pressure gauge, pressure canbe seen on the gauge itself.WARNING: Some pressure regulators do not have "push to lock",therefore simply turn the knob to adjust the pressure.MAINTENANCEBefore attempting any maintenance jobs on the compressor, make sureof the following:– Master power switch in position “0”.– Pressure switch and the control unit switches all off, in position “0”.– No pressure in the air tank.Every 50 hours of duty: we advise you to dismantle the suction filter andclean the filtering element by blowing compressed air on it (fig. 24).You are recommended to replace the filter element at least once if thecompressor operates in a clean environment, but more frequently if in adusty environment.In the “red-head” models (fig. 25) (TR200 – TR255), the suction filter islocated internally under the conveying cover (read-head). Unscrew thethree cover securing screws, remove the cover from the guard joint,remove the filter from its seat, and begin cleaning, blowing compressedair in opposite to normal flow direction.In the Silent model, the filtering element can be replaced by taking offthe soundproofing cabinet and proceeding in the same way as for theAB models (fig.29A).The compressor generates condensate water which accumulates in thetank.The condensate in the tank must be drained at least once a week, byopening the drain tap (fig. 26) under the tank.Take care if there is compressed air inside the cylinder, and water couldflow out with considerable force. Recommended pressure: 1 – 2 barmax.Condensate of compressors that are oil lubricated must not be drainedinto the sewer or dispersed in the environment as it contains oil.OIL CHANGES – TOPPING UP WITH OILThe compressor is filled with synthetic oil “FIAC Oil Synthesis”.We recommend a full change of oil in the pumping element within thefirst 100 hours of duty.The soundproofing cabinet is to be taken off first in the Silent model(fig.29A).Unscrew the oil drain plug on the housing cover, allow all the oil to flowout, and re-screw the plug (fig. 27 - 28).Pour oil into the upper hole of the housing cover (fig. 29 - 30) until itreaches the level indicated on the stick (fig. 9) or indicator (fig. 11)Pour oil into the upper hole of the head (fig. 30) in belt assisted unitsdesigned for topping up in that area.For the GM203 series, take the cap off and pour in 85 grams of oildirectly from the bottle (see fig. 30a).Once a week: check oil level of the pumping element (fig. 11) and see ifit needs topping up.For operation at ambient temperature in the range -5°C to +40°C, usesynthetic oil. The advantage of this oil is that is does not lose itscharacteristics either in winter or summer.Do not drain used oil into the sewer or dispose of it in the environment.OBSERVE THIS TABLE FOR OIL CHANGESTYPE OF OILHOURS OF DUTYFIAC Oil Synthesis...................................500Synthetic oil:AGIP Sint 2000 Evolution - BP Visco 5000 - ESSO Ultron -MOBIL Mobil 1 - NILS Dimension S - NUOVA STILMOILArrow5W50............................................400Other types of oil: mineral multigradeSAE 15 W40...........................................100WHAT TO DO IF SMALL MALFUNCTIONS OCCURLoss of air in valve under pressure switchThis trouble depends on poor tightness of the check valve – takethe following action (fig. 31):– Discharge all pressure from the tank- Unscrew the hexagon-head of the valve (A)- Carefully clean both the rubber disk (B) and its seat.- Refit all parts accurately.Air lossesThese can be caused by poor tightness of a union – check all unions,wetting them with soapy water.Compressor turns but does not loadCoaxial compressors: (fig. 32)- this may be due to failure of the valves (C1 – C2) or of a seal (B1 –B2): replace the damaged part.Pulley drive compressors: (fig. 33)- this may be due to failure of the valves F1 and F2 or of a seal (D1 –D2): replace the damaged part.GM 203 compressors:This may be due to the breakage of the valves (C1 - C2) or of thegasket (B1). Replace the damaged part (fig. 16A).- Check if there is too much condensate water inside the tank.Compressor no startingIf the compressor has trouble starting, check the following :- Does mains power match that of the data-plate? (fig. 14)- Are power cable extensions of adequate diameter or length?- Is the work environment too cold? (under 0°C)- For series VX/AB: was the thermal-breaker tripped? (fig. 20); in thesilent series (fig. 21)- Is there oil in the housing to ensure lubrication? (fig. 11)- Is power supplied to the electrical line? (sockets well connected,thermal- breaker, fuses in good condition).Compressor not stopping- If the compressor does not stop when maximum pressure is reached,the tank safety valve comes into operation. To repair the valve, contactyour nearest service centre.IMPORTANT- Do not on any account unscrew any connection while the tank ispressurised – always check if the tank is pressure free.- Do not drill holes, weld or purposely deform the compressed air tank.- Do not do any jobs on the compressor unless you have disconnectedthe power plug.- Temperature in operating ambient: 0°C +35°C.- Do not aim jets of water or inflammable liquids on the compressor.- Do not place inflammable objects near the compressor.- During down-times, turn the pressure switch to position “0” (OFF).- Never aim the air jet at people or animals (fig. 34)- Do not transport the compressor while the tank is pressurised.- Be careful with regard to some parts of the compressor such as thehead and delivery tubes, as they can reach high temperatures. Donot touch these parts to avoid burns.(fig. 18 - 19)- Transport the compressor, lifting or pulling it with the appropriate gripsor handles (fig. 4 - 6)- Keep children and animals well away from the machine operatingarea.- If using the compressor for painting:a) Do not work in closed environments or near to naked flamesb) Make sure there is adequate exchange of air at the place of workc) Protect your nose and mouth with an appropriate mask. (fig. 35)- If the electrical cable or plug are damaged, do not use the compressorand contact an authorised service centre to replace the faulty elementwith an original spare part.
